18.7.3.2  Pre-empting Existing Calls for E9-1-1 Calls 

If the ELIN device receives an E9-1-1 call from the IP network and there are unavailable 
channels (for example, all busy), the device immediately terminates one of the non-E9-1-1 
calls (arbitrary) and accepts the E9-1-1 call on the freed channel: 

 

SBC: The preemption is done only on a call pertaining to the same source IP Group 
from which the E9-1-1 call is received, or the same destination IP Group (i.e., PSAP 
Server). 

 

Gateway: The preemption is done only on a channel pertaining to the same Trunk 
Group for which the E9-1-1 call was initially destined. For example, if an E9-1-1 call is 
destined for Trunk Group #2 and all the channels belonging to this group are busy, the 
device terminates one of the calls in this group to free a channel for accepting the E9-
1-1 call. 

This feature is initiated only if the received SIP INVITE message contains a 

Priority

 header 

set to "emergency", as shown below: 

PRIORITY: emergency

 

 

18.7.3.3  PSAP Callback to Skype for Business Clients for Dropped E9-1-1 Calls 

As the E9-1-1 service automatically provides all the contact information of the E9-1-1 caller 
to the PSAP, the PSAP operator can call back the E9-1-1 caller. This is especially useful in 
cases where the caller disconnects prematurely. However, as the Enterprise sends ELINs 
to the PSAP for E9-1-1 calls, a callback can only reach the original E9-1-1 caller using the 
device to translate the ELIN number back into the E9-1-1 caller's extension number. 

In the ELIN table of the device, the temporarily stored 

From

  header value of the SIP 

INVITE message originally received from the E9-1-1 caller is used for PSAP callback. 
When the PSAP makes a callback to the E9-1-1 caller, the device translates the called 
number (i.e., ELIN) received from the PSAP to the corresponding E9-1-1 caller's extension 
number as matched in the ELIN table. 

The handling of PSAP callbacks by the device is as follows: 

1. 

When the device receives a call from the emergency service provider, it searches the 
ELIN table for an ELIN that corresponds to the received called party number in the 
incoming message.
